Satoshi-era bitcoin faces a bigger quantum threat after Google’s new Willow breakthrough
Google says its Willow chip can prepare the special quantum states needed for advanced calculations with about 40 times fewer errors, reducing one of the hardware bottlenecks behind any future attempt to crack bitcoin wallets.

DW NOTE
Google's Willow cut magic-state preparation errors by 40x, but only 8% of attempts succeeded and the chip remains orders of magnitude below the ~500,000 reliable states per second needed to attack a Bitcoin wallet. Satoshi-era coins remain vulnerable not because of Willow but because their public keys are already exposed — no quantum computer required to know where to aim once one exists.
